Meta API Error 80004 — Too Many API Calls
Meta API error 80004 means you have exceeded the rate limit. Learn how Meta rate limits work and how to implement proper throttling and backoff to fix this.
Meta API error 80004 means your app has exceeded Meta's API rate limit. Meta uses a "Business Use Case" rate limit based on your app's tier and the number of ad accounts it manages. Fix: implement exponential backoff, respect Retry-After headers, reduce call frequency, and batch requests where possible.
What Causes Meta / Facebook Error 80004?
Meta's Marketing API uses Business Use Case (BUC) rate limiting. Each app gets a pool of rate limit points that replenish over time. Consuming too many points triggers 80004. The response headers include X-Business-Use-Case-Usage with your current usage percentage.
- 1App polling the API too frequently (e.g. fetching stats every minute)
- 2Unbounded loops making API calls without throttling
- 3Multiple users in your app all triggering API calls simultaneously
- 4Large campaigns with many ad sets causing high call volume during sync
How to Fix Meta / Facebook Error 80004
- 1Check the X-Business-Use-Case-Usage response header to see your current rate limit consumption.
- 2Implement exponential backoff: on 80004, wait and retry with increasing delays.
- 3Respect the Retry-After header in the response — wait the specified number of seconds.
- 4Reduce polling frequency: use webhooks for real-time updates instead of polling.
- 5Batch multiple read operations: use the Batch Requests feature to bundle up to 50 API calls.
- 6Cache API responses and use conditional requests to minimize redundant calls.
